relation of k to ω, not generalized to a formula but always has some relation with the wave motion, e.g, ω = kv with v the speed of the plane wave.

group velocity is something I understood much less about.

From B&S 2.3.2, I see it is bound up in the relationship between k and ω, e.g.,
|
||
|
|
|
||
|
|
∂²/∂k² ω = β where k = k₀.

the fourier transformation gives a k-space function representation for an x-space wave function at a given time.
